Nowadays, organizational culture plays an important role in the process of developing and reconstructing an organization. The selection of an appropriate leadership style by the manager has a significant impact on the development and establishment of a favorable oragnizational culture which pave the ground for the organizations to compete with others. This is a descriptive study in which 28 managers including the bosses and their deputies in Isfahan University of Medical Sciences were selected in census. The data were collected by two questionnaires one for organizational culture and one for leadership style. The validity and reliability of the questionnairs were examined. Both descriptive [e.g percentage of frequency] and inferential statistics [e.g.chi.square, Fisherman exact test, Mann-Withney] were used to analyze the data. The leadership style was frequently cooperative in this study. There was a powerful organizational culture prevailing and there was no relationship between the manager's leadership style and different organizational cultures due to lack of variation in leadership styles and their demographic features. And neither was any relationship between different kinds of organizational cultures and the manager's demographic features when p-value is less than 0.05. The findings revealed that the managers did not have enough variations in their leadership styles. The managers should be able to choose an appropriate leadership style according to the specific situation they encounter
